High-power smart DC charging units optimized for isolated grids, commercial fleets, and tropical maritime weather conditions.
São Tomé and Príncipe (STP), an island nation characterized by its pristine ecosystems and reliance on imported fossil fuels for its thermal power systems, stands at a critical energy transition juncture. The Democratic Republic of São Tomé and Príncipe, under national energy policies supported by global development programs, aims to rapidly scale up its share of renewable energy. Transitioning transportation to Electric Vehicles (EVs) is not just a carbon-reduction strategy here; it is a vital economic imperative to reduce reliance on costly diesel fuel imports.
However, the local electricity grid managed by EMAE (Empresa de Água e Electricidade) faces structural limitations, including frequency fluctuations and grid capacity constraints. As a result, deploying standard high-power DC fast chargers directly into the local grid presents stability risks. Our range of specialized charging solutions bridges this gap by integrating photovoltaic solar generation, battery energy storage systems (BESS), and intelligent dynamic load management protocols. This enables robust charging hubs in São Tomé, Santo António (Príncipe), and key tourism/port hubs without overloading the national distribution grid.
To establish a reliable EV charging infrastructure network across the islands, three technical routes are recommended depending on local conditions:
Operating an EV charging network in an equatorial island environment like STP exposes electrical cabinets to continuous high humidity, extreme temperatures, and high-salinity air. Our solutions feature marine-grade outer shell coatings, IP65 (or IP54 minimum for outdoor chargers) ingress protection, advanced internal thermal circulation, and anti-corrosive treatments. This guarantees an operating lifespan exceeding 10 years, ensuring high reliability and a low Levelized Cost of Charging (LCOC).
Decouple your mobility infrastructure from the grid with integrated battery storage and smart monitoring platforms designed for private businesses, logistics, and eco-resorts.
We combine advanced research and development with flexible production lines to supply tailored products optimized for remote and emerging EV markets.
We develop our own charging control masters, allowing custom firmware, specific local grid protections, dynamic load management, and standard OCPP 1.6J/2.0.1 compliance.
Whether you require physical branding for local utilities (EMAE), custom localized software integrations, or custom paint jobs for luxury eco-resorts, our factories can scale production accordingly.
Our production facilities maintain global compliance, holding DEKRA CB, CE, ISO9001, and AAA credit ratings, verifying hardware reliability for long-term investments.

Answers to common engineering, logistics, and planning queries regarding EVSE installation on island grids.
Our off-grid systems, such as the Nancome 75kWh and 100kWh models, utilize oversized battery storage (BESS) and high-efficiency hybrid solar charge controllers. The energy management system (EMS) tracks weather trends via internal sensors or cloud APIs, scaling back maximum station power draw dynamically while preserving battery reserve capacity to ensure basic operations through periods of low solar output.
Yes. Our industrial charging stations feature wide input voltage windows (+/-20%) and standard grid isolation protection. For areas prone to grid instability, we recommend installing our chargers with a built-in battery storage buffer. The battery charges steadily at a lower power rating and discharges rapidly to charge the vehicle, shielding the grid from peaks and the vehicle from voltage surges.
We construct multi-standard chargers containing CCS2 (European standard), CCS1 (American standard), and GBT (Chinese standard). Given that STP typically imports vehicles from multiple regions (particularly Europe and China), our dual-connector units allow charging for a wide variety of EV models concurrently.
We use robust outdoor enclosures rated up to IP65, built with galvanized sheet steel or aluminum alloy coated with C5-M marine-grade anti-corrosive powder coatings. Internal circuit boards are treated with conformal coatings to block out ambient humidity, preventing galvanic corrosion on solder joints.
Yes, all models support OCPP 1.6J (upgradable to OCPP 2.0.1) over 4G LTE, Wi-Fi, or Ethernet. Operators can monitor session data, handle user authentication (RFID/App), manage dynamic load control, and push remote firmware updates through their chosen Central Management System (CMS).
We provide full export-import coordination to transport equipment safely to the Port of São Tomé (Ana Chaves Bay) and São Tomé International Airport (TMS). Packaging follows sea transport guidelines, including vacuum-sealed barrier bags and shock-resistant wooden crates to protect electronic components from ocean air exposure.
Our customer service department provides technical documentation, detailed electrical schematics, and interactive installation guides. Local electrical contractors can work directly with our engineering department online to ensure smooth installation, grid testing, and commissioning.
